3. EXISTING CONDITIONS 3.1 Existing Streets and Utilities The proposed improvements addressed in this report is the last in a series of projects providing necessary street, trail and trunk utility improvements required to serve numerous commercial and residential developments in the immediate area. The proposed Puma Street improvements are being driven by two residential development projects, one on each side of Puma Street south of Alpine Drive, including Alpha Development by AKM Farm/Paxmar, and Riverstone 4th Addition by Capstone Homes. Figures showing the locations and scope of both developments are included in AppendixA. In 2006, Bunker Lake Boulevard was improved west of Armstrong Boulevard. The easterly 2,650 feet or so was constructed with trunk 18-inch polyvinyl chloride (PVC) sanitary sewer and 16-inch ductile iron pipe (DIP) watermain under a permanent bituminous pavement section. The westerly 1,400 feet or so of Bunker Lake Boulevard to Puma Street, as well as all of Puma Street between Bunker Lake Boulevard and Alpine Drive, was constructed without trunk utilities and only a temporary pavement section generally consisting of 3 inches of aggregate base under 2 inches of bituminous pavement. Based on future demand, trunk utilities were ultimately proposed to be extended to and along Puma Street, after which the temporary pavement sections would be replaced with permanent pavement sections. In the fall of 2017, municipal utility extension improvements were constructed along the westerly 1,400-feet or so of Bunker Lake Boulevard to Puma Street. These trunk utilities were required to serve portions of the new Riverstone residential development west of Puma Street, as well as a portion of the new Bunker Lake Industrial Park development south of Bunker Lake Boulevard. In March of 2017, Bolton Menk updated their Future Business Park study to include concept designs and estimated costs for extending trunk utilities to Puma Street. A copy of the updated report is attached in Appendix D of this report. In late 2017 through early 2018, trunk utility improvements were extended along Puma Street, north of Bunker Lake Boulevard. These utility improvements were required to serve a majority of the Riverstone residential development, future commercial and residential development east of Puma Street, plus some undeveloped land in the Northfork development, west of the Riverstone development. These development areas are all designated as municipal urban service areas (MUSA) thereby requiring service by City sewer and water. In the summer and fall of 2018, permanent street sections were constructed on the sections of Bunker Lake Boulevard and Puma Street where the trunk utility improvements were recently constructed.
